## springboot+redis+nginx 解决session共享 ##

Nginx负载均衡解决方案：[https://blog.csdn.net/my13413527259/article/details/85234186][https_blog.csdn.net_my13413527259_article_details_85234186]

\-----------------------正事专用分割线-----------------------

**pom.xml**

引入组件

<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-data-redis</artifactId>
    		</dependency>
    		<dependency>
    			<groupId>org.springframework.session</groupId>
    			<artifactId>spring-session-data-redis</artifactId>
    		</dependency>

**application.yml**

配置连接redis

server:
      port: 8102
    spring:
      redis:
        password: 123456
        cluster:
          nodes:
          - 127.0.0.1:7001
          - 127.0.0.1:7002
          - 127.0.0.1:7003
          - 127.0.0.1:7004
          - 127.0.0.1:7005
          - 127.0.0.1:7006
      session:
        timeout: 300

**SessionConfig.java**

开启redis管理session

import org.springframework.context.annotation.Configuration;
    import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
    
    @Configuration
    @EnableRedisHttpSession
    public class SessionConfig {
    
    }

**TestControl.java**

模拟登陆，设置到session

@Controller
    public class TestControl {
    	
    	@GetMapping("/index")
    	public String index() {
    		return "main";
    	}
    	
    	@GetMapping("/login/{name}")
    	public String login(@PathVariable("name")String name,HttpServletRequest request) {
    		System.out.println("002----name----"+name);
    		request.getSession().setAttribute("name", name);
    		return "redirect:/index";
    	}
    
    }

**main.html**

展示登陆信息，session中的数据

<!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    8102----nginx002
    <h2>name:<span th:text="${session.name}">name</span></h2>
    </body>
    </html>

分开部署两份。修改一下页面区分哪个服务器

**测试**

请求：[http://192.0.0.234/login/333][http_192.0.0.234_login_333] ，模拟登陆一次

跳到主页 [http://192.0.0.234/index][http_192.0.0.234_index] ，刷新几次，模拟负载到不同的服务器上

如果取到登陆信息，说明session共享成功;

**redis中会有session的信息**
